Pre-hopped maybe? If so, I would go ahead and take a shot - I've heard over the years of all sorts of odd ideas that worked out just fine. My favorite is the guy who used bread yeast because he didn't have brewing yeast on hand. This would be practically main stream by comparison.
If my guess is correct [edit - which it turned out to be], then I suggest trying unhopped extracts in the future and do your own hop additions.
